The Romans and Greeks labelled those outside their borders as barbarians uncivilised brutes who needed to be conquered for fears of them contaminating the empire.

罗马人和希腊人把他们境外的人称为野蛮人，未开化的野人，因为担心他们污染帝国，所以必须征服他们。

In regard to the domestic animals kept by uncivilised man, it should not be overlooked that they almost always have to struggle for their own food, at least during certain seasons.

对于野蛮人饲养的家畜， 不容忽视的是， 它们几乎总是要为自己的食物而奋斗， 至少在某些季节是这样。
